WEB-CUTTING MECHANISM FOR CANE-LOOMS.

Specification of Letters Patent.

Patented Nov. 23, 1909.

Application led February 23, 1909. Serial No. 479,625.

To all whom it may concern:

Be it'known that I, JOSEPH TILP, a citizen of the Empire ofAustria-Hungary, residing in Hoboken, in the county of Hudson and Stateof New Jersey, have invented certain new and useful Improvements inleb-Cutting h/lechanism for Cane-Looms, of which the following is aspecification.

This invention relates to mechanism for cutting the webs of differentfabrics, but more particularly woven cane-fabrics, and the mechanism isprimarily designed for application to cane-looms, taking the form of anattachment which can be readily embodied in cane-looms of the well-knowntypes either at the time these looms are manufactured or at anysubsequent time. However, although the mechanism is described as used inconnection with a cane-loom, it may be used for other purposes.

The object of the invention is to provide a mechanism by which thefabric which is woven by the loom can be sheared at its sideedge, inorder to present a perfectly straight, trimmed edge, or, if desired, thefabric may be divided into two or more parts simply by the addition ofanother pair of cutting disks to the shafts with which the mechanism isprovided. These shafts, upon which any desired number of rotary cutting`devices may be arranged, are rotated through a positive connection withthe operative parts of the loom and the cutting devices move inconsonance with the feed-roll so that the proper speed is imparted tothe cutting devices in relation to the rapidity with which the fabric isfed. A fixed relation between the speeds of the cutting devices and ofthe feed-roll is at all times maintained.

In the accompanying drawing, Figure 1 is a front-elevation of a loomprovided with web-cutting mechanism constructed accord ing to theinvention, Fig. 2 is a side-elevation of the loom, Fig. 3 is a detailelevation of the cutter-shafts and the cutters thereon, and Fig. 4f isan end-view of Fig. 3.

Similar characters of reference indicate corresponding parts throughoutthe several figures of the drawing.

In the drawing the loom is shown as being of the well-known type, havingside-frames 5 at the upper front-portion of which a roller 6 guides thefabric which is woven by the loom downward to a feed-roll 8, likewise journaled in the side-frames 5. Below the feedroll is located thewinding-up roll 9, as shown in Fig. 1, this roll receiving the fabricfrom the feed-roll after taking the course indicated by the dotted line10 in Fig. 2.

The feed-roll and the winding-up roll are connected, as is usual inmachines of this character, by a train of gears embodying a gear 11fixed to the feed-roll shaft 12, as shown in Fig. 1.

The improved web-cutting mechanism is driven from the gear 11, that isto say, the feed-roll gear, and comprises two parallel shafts 18, 14rotatable in suitable brackets carried by the side-frames of the loom atthe front thereof, and these shafts are located in the same horizontalplane slightly above the feed-roll, as shown in Fig. 1. Motion istransmitted to the outer shaft 13 by means of a gear 15 on said shaftmeshing with the feed-roll gear 11. At the end opposite the gear 15there is a gear 1T on the shaft 13 meshing with a gear 16, so that theshafts 13, 14 rotate together. Also, as the gears on the shafts are ofthe same diameter the shafts will rotate at the same speed.

In the embodiment shown in the drawing, there are arranged on the shafts13, 141 two cutting devices, each consisting of a pair of rotarycuttingdisks, the disks of one pair coacting to cut the woven fabric atthe edge of the same, while the disks of the other cutting device serveto sever the fabric in a straight line to divide the same centrally. Anynumber of such pairs of cutting disks may be employed, but as they areall alike it will only be necessary to describe one of the cuttingdevices, such as shown in Fig. 3. On the shaft 18 is adjustably applied,by means of a split sleeve 18 and bolt 19, a rotary cutting disk 20having a series of circumferential shearing teeth 21, as shown in Fig.4;, coacting with a similarly mounted disk 22 on the shaft 14 having arightangled cutting edge 23, as shown in Fig. 3, with which edge theteeth 21 coact in such a way as to cut the strands of the wovencanefabric. The plain cutting disk 22 is formed integral with a sleeve24 and provided with a clamping bolt 25, these parts 24, 25corresponding with the sleeve 18 and bolt 19 of the toothed disk 20. Bymeans of the split sleeves and their clamping bolts the disks may beslid along` the shafts and secured in the desired position so as to cutthe fabric at any point.

ing the cutting disks out of coperation with each other, I find itadvisable to provide the.

shafts with a frictional connection 26, which may be of any preferredform, but is illustrated as a hook having an eye 27 fitting about oneshaft, while Vthe hooked end 28 frictionally grips the other shaft, thedisengagement of the hook from the shaft being prevented by a small pin29. This device holds the shafts at exactly the distance from each otherto insure the proper engagement of the cutting disks.

In the operation of the machine the movement of the feed-rollnecessitates a correspending movement of the two geared shafts 13, 14,which rotate at the same speed and cause the pairs of cutters to cut thefabric at points depending on the positions in which such cutters areadjustably clamped, and in this way the trimming of the fabric at theedge, or its division into two or more parts, can be readily andefliciently accomplished. As indicated by the dotted lines in Fig. 2,the woven fabric passes between the shafts 13 and 14; and thence to thefeed-roll, so that the fabric is cut before it reaches the latter.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. In a cutting mechanism, the combination of a pair of parallel shaftshaving intermeshing gears, a plurality of cutting disks separately,longitudinally, adj ustably mounted on each of said shafts and adaptedto cooperate with each other, a connection having an eye forming abearing fitting about one of said shafts and having a U-shaped hookadapted to fit over the other shaft, and a pin passing through the endsof the U- shaped hook for holding the shaft in the hook.

2. In a cutting mechanism, the combination of a pair of parallel shaftshaving intermeshing gears, a plurality of cutting disks separately,longitudinally, adj ustahly mounted on each of said shafts andcooperating with each other, a connection having an eye at one endforming a bearing and fitting about one of said shafts, the other end ofsaid connection being provided with a U- shaped hook in which the othershaft is engaged, the ends of the arms of said hook being provided withalined perforations, and a pin passing through said perforations andholding said hook on the shaft.

In testimony, that I claim the foregoing as my invention, I have signedmy name in presence of two subscribing witnesses.
